Physics

I literally failed in physics and scored a good 0. I was called to my physics teacher's office. I couldn't care less and started to go home but suddenly someone holds my collar and pulls me. To my surprise it was my physics teacher. She asked me where I was going but didn't even hear my answer and dragged me into a class. I argued saying I need to go home and didn't care about marks. She was so frustrated she slapped so hard I lost my senses. She pulled my ear and said that she's gonna punish me till i learn a lesson and had already told my parents I will be staying back to improve my marks. I resisted and tried running but the door was closed from outside. She started laughing. I begged her to let me go. She said "not so fast my brand new ****"
